An automatic retainer valve includes a body defining a piston passageway and at least one piston positioned within the piston passageway, a brake pipe and reference volume in fluid communication with a first end of the valve, a brake cylinder in fluid communication with a second end of the valve, and an exhaust port defined in the body and positioned between the first and second ends of the valve. Pressurized fluid may be vented from the brake cylinder via the exhaust port upon a brake cylinder pressure exceeding a reference volume pressure. The brake cylinder pressure may push the at least one piston towards the first end of the valve until the brake cylinder pressure equalizes with the reference volume pressure.
